Example of 232/485-CAN converter_GCAN
4 Examples
4.1 Transparent conversion
1. Serial port→CAN
GCAN-201 will send the serial data to CAN-Bus immediately if GCAN-201 receive the serial data.
E.g. Serial data 11 22 33 44 55 66 77 88 converts to CAN-Bus. Frame ID is the configuration for“发送标识符” which users have set. Frame data is 11 22 33 44 55 66 77 88.
2. CAN→Serial port
GCAN-201 will send the CAN data to serial port immediately if GCAN-201 receive the CAN data
E.g.： Check“允许 CAN 帧信息转发到串行帧中” and“允许 CAN 帧标识转发到串行帧中”which means the CAN frame information （帧信息） and the frame ID（帧标识） will display in the serial frame.
CAN frame is standard data frame. Frame ID is 00 01. Frame data is 11 22 33 44 55 66 77 88. GCAN-201 converts to Serial port. Serial data is 08 00 01 11 22 33 44 55 66 77 88.
4.2 Transparent conversion with identity
Transparent with identity transformation is the special usage of Transparent conversion.
1. Serial port→CAN
Users can set the start position address and the length of the CAN frame ID in the configuration.
E.g.： If the CAN frame ID starting position address is 1, the length is 2 in the Serial frame. Serial frame data is 01 23 33 44 55 66 77 88. GCAN-201 converts to CAN. CAN frame ID is 123, and
frame data is 33 44 55 66 77 88.
2. CAN→Serial port
E.g.： If the CAN frame ID starting position address is 1, the length is 3 in the Serial frame（ Extension frames） . Conversion is shown as Figure below.
